I would suggest the backlash would likely be due to the wording of your original comment.
you stated that "Programmer humor is really cringey."
Cringey is generally a negative sentiment and saying "is" implies that this negative sentiment is a generally accepted fact.
I'd suggest that humour is almost entirely subjective, and therefore attempting to suggest that any form of humour is objectively bad makes no real sense.
If you had said "I find programmer humor to be really cringey" you may well have received fewer negative reactions.
